This lunar event is important as it is happening after 150 decades. Such a celestial event last took place in 1866.

According to a previous report, the moon rotates in an elliptical orbit round the Earth. When it comes partially in the shadow of the Earth, it is referred to as the penumbral phase. Soon as it pertains fully in the shadow of the Earth it is known as the umbral phase.

This is followed by the Supermoon. When the moon is closest to the earth, which is also known as its perigee point, it’s known as the Supermoon.

Finally, once the sun, moon, and the earth come in a direct line, it’s called full moon. But when two full moons happen in a gap of 29.5 days, in other words, in 1 month, it is known as Blue Moon.

In 2018, one full moon had occurred on 1 January and the next is slotted to be on 31 January. Thus, on 31 January, together with the lunar eclipse, Supermoon, a Blue moon will also happen.

Since the lunar event is expected to take place during the night, the moon will not go into total darkness, instead the light will be scattered and may appear reddish. Thus the title Blood Moon, for the way the moon will look on 31 January.
